Application filed December 1, 1909. Serial No. 530,882.

To all whom it may concern:

Be it known that I, ALBERT O. PAULSON, a citizen of the United States,residing at i Los Angeles, in the county of Los Angeles,

both lateral and fore and aft stability in an airship, and as it is wellknown in the art that the box kite possesses the most stable form forhorizontal translation, I have adopted together with ceratain improvedfeatures which at once renders it more available for verticaltranslation.

One of the great dihiculties inherent in the box kite formation is theinability to change the direction or the angle of flight, and to thisend I have provided a simple and eflicient means whereby the structuremay be directed through the air at any desired inclination from thehorizontal, or it may be easily turned in either direction while inflight, without requiring any appendages, such as movable horizontalplanes or rudders, as will now be set forth in detail.

In the drawings, Figure 1 is a side elevation of my improved airship.Fig. 2 is a top or plan view. Fig. 3 is a view of the front end of theairship. Fig. 4 is a perspective view of one of the box kite elements.Fig. 5 is a side view showing detail of mechanism for changing the angleof the Q propeller shaft; and Fig. 6 is an end view showing details ofthe mechanism for changing the angles of the shaft.

In constructing my invention I provide a frame, which in this instancecomprises two horizontal parallel bars 5, a suitable distance apart,joined at their ends, and having, preferably, at the forward end twowheels 6, and a single wheel 7 at the rear end. The engine is mounted onthis frame a little to the rear of the middle portion, and a shaft 9extends forwardly through a vertically-movable bearing 10, terminatingat a propeller 11, which is mounted thereon. The shaft has a universaljoint 9 near the engine, so the forward end of the shaft may be raisedor lowered, a pair of hinged links 8 having their lower ends journaledto the axle shaft, and their upper ends to the bearing 10, and thebearing 10 is adapted to move vertically in a guide 10 An operating bar11 attached to the hinged connections of these links, extend back to theoperator and has a handle 12 by means of which the shaft 9 may be raisedor lowered.

The supporting surfaces are two box kites, mounted diamond-shaped and somounted on the frame as to have an edge at the top and bottom. Theforward kite 12 has its lower sides, or the corner thereof, cut away awidth equal to the distance between the frame members 5, andapproximately midway between its ends are downwardlyprojecting ears 13which are secured to the frame members by pivot pins, so the upper endof the box kite will swing fore and aft a limited distance.

The rear box kite ll is similarly cut away at its lower corner or edge,and has at its upper corner or edge an arm 15 which has a socket toreceive therein a vertical post or rod 16. The lower end of this rodrests in a gudgeon 17 on the frame, and an eye on the frame, (notshown), holds the lower end of the box kite in alinement. Thisconstruction permits the rear end of the box kite to swing laterally. Inorder to hold the rear box kite in position the frame members areprovided with two cross pieces 18 19, which project beyond the frame asuitable distance, and posts 20 21 extend upwardly from the ends ofthese cross pieces converging at an eye 22 through which the verticalrod 16 passes. Suitable stay wires 23 21 extend from the end of thesecross pieces to the frame fore and aft.

Toggle jointed levers 25 26, secured to the eye 22, on the rear kite, at27, hold the front kite in position. An operating arm 28, hinged to atoggle jointed connection, extends down to the region of the operator,and the inclination or angle of the front box kite can thereby beregulated at will.

The rear box kite may be swung in either direction by means of cables29, which are attached to the outer corners of the kite, and thesecables extend down to the ends of the cross pieces 19 and thence to anypoint (not herein shown) within reach of the operator.

The box kites are similarly constructed, as each has a lateral rigidwing at the outer corners, and within is a pair of transversely-disposedsupporting surfaces 81 in the form of blades, narrow fore and aft, asshown. It will thus be seen that while the two kites are normally inalinement with each other, they may be adjusted independently of eachother, the forward one to give the angle of flight, and the rear one todirect it laterally.

In order to provide a more efficient means to utilize the supportingsurfaces while in vertical translation, the open or cutaway portion inthe bottom of the kites aflords means of admitting air, and by addingthe 7 surfaces 30 31 a much larger efficient surface is obtained forpractical work than would be possible if the kites were closed up asusually constructed. The structure can in this manner be madeexceedingly light and compact, assuring the utmost stability fore andaft and laterally, while utilizing every available surfacefor sustainingpurposes while in flight.

The angled disposition of the sides of the kite members from thevertical are at such in clinations as to afford the utmost stability,since they serve as dihedral angles more efficiently than if the sidesthereof were vertical.

When the angle of the forward box kite is changed, or when it is desiredto launch the ship, the relative angle of the propeller shaft may bechanged by means of the operating bar 11 which is moved back or forth atthe will of the operator.

What I claim as new, is:
